Ovarian cancer, a prevalent malignant tumor, is commonly treated with platinum-based drugs as the first-line therapy. However, the increasing use of these drugs has led to a rise in platinum resistance. Statistics indicate that around 30-50% of ovarian cancer patients develop resistance to platinum-based drugs after treatment. Consequently, it is crucial to explore the mechanisms of platinum resistance in ovarian cancer to gain a better understanding of its occurrence and progression.

At present, the formation of platinum resistance is believed to involve various factors, such as the cell's DNA repair capacity, cell apoptosis pathway, and expression of transport proteins. In-depth research on these mechanisms can provide valuable evidence for the discovery of new treatment strategies. The development of platinum resistance often correlates with the abnormal activation of intracellular signaling pathways. Therefore, investigating platinum resistance in ovarian cancer can aid in identifying novel therapeutic targets and drugs.

Moreover, comprehending the situation of platinum resistance in ovarian cancer is advantageous for the clinical development of personalized treatment plans. Different patients exhibit varying degrees of resistance to platinum-based drugs. Hence, understanding the resistance status of each patient can assist doctors in selecting more suitable treatment plans and enhancing treatment efficacy.
